SPECIFICATION forming part of Letters Patent No. '789, i7'2, dated May9, 1905,

Application filed February 18, 1905. Serial No, 246,231.

To all who/11, it may concern:

Be it known that we, EVERETT S. 001) and J ONAS Non'ruuor, citizens olthe United States, and residents of Hopedale, county of 'orcester, Stateoi? Massachusetts, have invented an lmprovement in Filling-Exhaustionlndicatiiig and Controlling Mechanism for Looms, of which the followingdescription, in connection with the accompanying drawings, is aspecilication, like characters on the drawings representing like parts.

This invention has for its object the prod uction of novel andaccurately operating mechanism to positively control and effect a changein the operation of a loom when the filling in the running shuttle hasbecome substantially exhausted or woven off to a prede termincd extent.The change in the operation of the loom may be the automatic stoppagethereof to enable the Weaver to provide the running shuttle with a freshsupply of filling, or it may be the actuation of mechanism toautomatically e'l'l'ect replenishment of the running filling withoutstopping the loom. Replenishment of the running filling automaticallymay be elfected by mechanism of thefiNorthrop type, shown in UnitedStates PatentNo. 529,940 and others, wherein a fresh supply of fillingis inserted automatically in a running shuttle of the automaticallyselfthreading class without stopping or varying the speed of the loom.As such looms are in extensive use, we have herein illustrated onepractical embodiment of our invention in connection with a loom providedwith automatic filling-replenishing mechanism of the Northrop typehereinbeiore referred to.

The filling-exhaustion-indicating mechanism in the present embodiment ofour invention comprehends two movable members, one of whichintermittingly impinges on and is moved by means within the shuttleuntil the running filling is exhausted to a predetermined extent, and anactuator operatively connected with such member mounted on and movablerelatively to the other member into inoperative position by theintermitting movement of the first-named member. The member on which theactuator is mounted is 111m able by impingement on a vibrating part ofthe loom only when the predeterl'niued exhaustion of the fillingpermits, thereby causing the then relatively quiescent andoperativcly-positioned actuator to effect the actuation of mechanismwhich controls the operation of the loom. Inasmuch as one of the memberssupports or carries the other member, we have hereinafter designated theformer as the carrier, and the member supported thereby is termed the'fceler, as it intermittingly impinges upon and feels the filling in therunning shuttle to indicate the volume thereof or, in other words, itsdegree of exhaustion. Up to the point of predetermined exhaustion of thefilling the 't'eeler acts on each feeling movement thereof to move theactuator relatively to the carrier on which it is mounted and rendersthe actuator inoperative. WVhen predetermined filling exhaustion isreached, however, the feeler becomes dead or inert with respect to bothfilling and actuator, and hence is ineffective to render the actuatorinoperative, and the same remains quiescent with relation to thecarrier. At such time the carrier is impinged on and moved by avibrating part of the loom, such as the shuttle, and the relativelyquiescent actuator is moved with the carrier as a unit to effect theactuation of the controlling mechanism for the loom. The construction issimple, direct, and positive in its action and so arranged that thechange in the operation of the loom is impossible until the filling inthe running shuttle is exhausted to the predetermined extent. Hereinthere is no pressure whatever on the filling carrier or bobbin at theinstant of filling replenishment, for such operation is effected whenthe shuttle engages the carrier or a part fixedly mounted thereon, thefeeler at such time being dead or inert and performing no work.

The various novel features of our invention will be fully described inthe subjoined specification, and particularly pointed out in thefollowing claims.

Figure 1 is a top or plan view of a portion of the left-hand side of aloom with one embodiment of our invention applied thereto, the runningshuttle being in position for cooperation with thelilling-exhaustion-indicating mechanism on the forward beat of the lay.Fig. 2 is a left-hand side elevation of the mechanism shown in Fig. 1with a portion of automatic filling-replenishing mechanism shown at theopposite side of the loom. Fig. 3 is a rear elevation of the transmitterintermediate the feeling devices and the replenishing mechanism to bedescribed. Fig. L is an inner side elevation, enlarged, taken at theleft of the line f a, Fig. 1, of the feeling devices and a portion ofthe transmitter. Fig. 5 is a much-enlarged longitudinal section on theline 5 5, Fig. 1, taken through the center of the carrier, the partsbeing in normal'position. 6 is a transverse section on the line 6 6,Fig. 5; and Fig. 7 is a top or plan view of the carrier and feeler, aportion of the actuator being broken off to show the part beneath it.

The filling-feeder F, Fig. 2, mounted on the breast-beam A and adaptedto contain a supply of filling carriers or bobbins b, the transferrerfto transfer them one by one to the automatically self-threading shuttleS, and the controlling rock-shaft (Z to effect the re plenishment offilling may be and are all substantially as in the Northrop patentreferred to, an upturned arm 4", fast on the rockshaft, having pivotallyconnected with it a rearwardly-extended latch (Z to at times cooperatewith a vibrating actuator, shown as the weft-hammer 1V. lVhen the rearend of the latch is moved into the path of the head W, it enters arecess w therein, (see dotted lines, Fig. 2,) and the forward movementof the weft-hammer pushes the latch forward, acting through arm (Z toturn the rock-shaft (Z in the direction of arrow 200, Fig. 2, to effeetthe operation of the replenishing mechanism in well-known manner. Theactuator, latch, rock-shaft, and intervening connections constitutecontrolling means for the loom and herein operate to gox'ern the time ofoperation of the replenishing mechanism.

Novel filling-exhaustion-indicating mechanism elfects the actuation ofthe controlling means when and only when the lilling in the shuttle hasbecome exhausted to a predetermined extent, so that it is impossible toeject a bobbin from the shuttle until the filling has been woven off tothe desired extent, thus greatly reducing waste, and, on the other hand,when the predetermined exhaustion is attained a fresh supply of fillingis with certainty provided, so that there will be no pick devoid orpartly devoid of filling.

The shuttle S has an opening 1 in its side wall (see dotted lines, Fig.1,) to register with the usual opening 1 (see 1) in the front wall 2 ofthe shuttle-box 3 when the shuttle is properly boxed therein.

The notched holding-plate 4 for the shipper S is depressed at its outerend at 5 to support a vertically-adjustable bracket 6, having aninclined top 7, on which is adjustably secured by screws 8 a stand 9. Byinclining the bracket-top T the stand is so inclined that the feeler, tobe referred to, moves in a path closely coincident with the path of thelay A as it swings back and forth, so that filling in the shuttleimpinging on the feeler acts substantially directly along its path ofmovement, obviating any bending or twisting tendency and impartinggreater accuracy to the operation of the apparatus. In Fig. 2 theshipper is omitted for the sake of clearness of illustration. The standis conveniently made in two parts bolted together and chambered out at10, Fig. 5, to receive a transverse and rectangular enlargement 11 onthe carrier, which forms one member of the filling-exhaustionindicatingmechanism. The carrier (see Figs. 5 and 7) is preferably made as a flatelongated plate 12 of metal, having at its rear end a lateralenlargement or head 13 and at its forward end the enlargement 11, beyondwhich there is a preferably cylindrical shank 1 1, freely slidablethrough an opening in the front end of the stand 9. The enlargement llslides freely in the chamber and is guided by the sides and top thereof,and a spring 15, coiled i around the shank 1 1 between said enlargementand the front end of the stand, serves to move the carrier rearward intothe position shown in Fig. 5, the rear end of the stand limiting suchmovement. Said end 16 has an opening 17, Fig. 6, to receive the bodyportion 12 of the carrier and slidably support it. Upturned parallelcars 18 on the rear end of the carrier adjacent its head are connectedby a crosspiece 19, having a threaded hole 20 to receive the threadedshank of a hunter 21, adjustable in the cross'piece and held in adjustedposition by a check-nut 22. The flat body 12 is centrally andlongitudinally slotted at 23 from the head 13 to the enlargement 11, andadjacent the latter short parallel guideways or flanges 24 are formed onthe sides of the slot. \Ve have herein shown an actuator movably mountedon the carrier, said actuator being made as an elongated arm 26,fulcrumed between the ears 18 on a horizontal pin 27, and having a shortlug 25 depending below the fulcrum, the actuator 26 being extendedforward above the carrier and prolonged to project above the top of thestand 9, as clearly shown in Fig. 5.

The third member of the filling-exhaustionindicating mechanism is thefeeler, and herein it comprises a broadened head 28 and an elongatedshank 29, the feeler being made of metal and light in weight. its headbeing recessed transversely on its under side at 30 to receive the head13 of the carrier. The feeler-shank freely enters the slot 23 and at itsforward end rests upon the guideways 24 within the opening 16, the shankpassing under the crossbar 19 and between the cars 18, as shown. A veryslight longitudinal sliding movement of the feeler upon the carrier isprovided by making the forc-and-aft width of the recess 30 greater thanthe distance from front to rear of the carrier-head 13, as clearly shownin Fig. 5. We have provided a positive connection between the feeler andthe actuator 26 by introducing the lower end of the lug 25 betweentransverse shoulders 31 on the feeler-shank, (see Fig. 5, and owing tothe great difference in lever-arms, comparing the lug 25 and actuator26, the slight forward movement of the feeler on the carrier issufficient to elevate the tip of the actuator a considerable distanceabove the top of the stand 9. Consequently when the lay beats up and theshuttle is boxed in the shuttle-box 3 the feeler will enter the shuttleand impinge upon the filling, and the feeler will thereby be movedforward relatively to the carrier. The slight distance permitted by theclearance of the head 13 in the recess 30 before the continued forwardmovement of the lay will move feeler and, carrier in unison against theaction of the spring 15. This initial filling induced and relativemovement of the feeler acts through the lug 25 to inoperatively positionthe actuator 26 by swinging it upward in the construction hereinillustrated, so that when the carrier begins to move forward with thefeeler the actuator will be inoperative and will remain so during theforward stroke of feeler and carrier. On the return stroke, the layswinging back, the spring 15 serves to return the carrier to theposition shown in Fig. 5, and after the filling recedes from the feelerthe weight of the actuator 26 returns it to normal position and throughlug 25 sets the feeler in impinging position in readiness for the nextfeeling stroke. Until such time as the filling in the shuttle isexhausted to a predetermined extent the feeler and carrier will be movedoutward intermittingly, first inoperatively positioning the actuator oneach active stroke, the amplitude of filling-induced movement of thefeeler and carrier gradually decreasing as the diameter of the yarn masson the filling carrier or bobbin diminishes. As such amplitude ofmovement decreases the distance between the bunter 21 and a vibratingpart of the loom, such asthe front side wall of the shuttle, alsogradually decreases, so that when the desired or predetermined fillingexhaustion is reached the hunter will impinge upon the shuttle. At thatinstant the diminution in the diameter of the yarn mass permits thefeeler-head to extend so far into the shuttle that there can be nofilling-induced movement of the feeler, the latter thus lying dead orinert on the carrier, and consequently the actuator will remainquiescent with relation to the carrier and in its operative position.Then the continued forward movement of the lay as it completes itsstroke will move the carrier and actuator forward together as a unit,the inert feeler maintaining the position relative to the carrier shownin Figs. 5 and 7. The means for causing the forward movement of theoperatively-positioned actuator to effect a change in the operation ofthe loom will now be described. It is to be observed, however, thatwhile there is sufiicient filling in the shuttle to impart movement tothe feeler by impingement thereon such movement will cause the actuatorto be inoperatively positioned, so that no change in the operation ofthe loom can be effected until just the desired point of exhaustion offilling is reached. By means of the adjustment of the hunter 21 thequantity of filling remaining at such time is regulated to a nicety, andthe indicating mechanism is also thereby adjusted for bobbin di ameterand width of shuttle.

The plate 4. is provided with an upturned car 32, which carries afulcrum-stud 33, Figs. 1 and 3, substantially parallel to the path ofmovement of the reciprocating carrier 12 14C, and on said stud isfulcrumed a transmitter (shown as a lever 34 35) operatively connectingthe latch (Z and the filling-feeling device. The free end of the arm 34extends beneath the latch and normally sustains it in inoperativeposition, a lug 36 on said arm then resting on the top of thebreast-beam. (See Fig. 3.) At the opposite or outer end of thetransmitter the arm 35 is bent laterally and forms an upright car 37(clearly shown in Fig. 1) adjacent a guide 38 on the stand 9, the earhaving a cam-slot 39 therein. A controller for the transmitterisprovided in positive and sliding connection therewith and so constructedthat the movement of the transmitter from inoperative to operativeposition, or vice versa, is effected positively, the controller lockingsaid transmitter in either position. The controller is shown best inFig. if as an arm 4L0, fulcrumed on an upright stud il, carried by abracket 12, secured to the ear 32, the studs 33 and 4:1 beingsubstantially at right angles to each other. The free end of thecontroller passes through the cam-slot 39 and under the guide 38 acrossthe top of the stand 9, the controller end or foot 13 extending into theoperative path of movement of the actuator 26, the rear edge of the footbeing shown as notched, as at 44, (see dotted lines, Fig. 5,) while thefree end or tip of the actuator is beveled on both sides or brought toan edge, at 5. 1 f the parts are in the position shown in Fig. 4:, thecontroller being then in the low portion of the cam-slot 39, it will bemanifest that movement of the controller to the left or toward the frontof the loom will act through the cam-slot to depress the adjacent end ofthe transmitter and rock the latter on its fulcrum The arm 34 is therebyelevated, and the latch (Z is moved into position to be engaged by itsactuator vin,

the wefthammer as hereinoefore referred to. Inasmuch as the peculiarconnec tion between the controller and transmitter locks the latterinposition, itwill be manifest that the transmitter will be unaffected byshock or jar and can only be operated or rocked through movement of thecontroller. Remembering that so long as there is sufficient filling inthe shuttle the impingement of the feeler upon the filling will move theactuator into inoperative position with its sharpened tip 45 above thefoot 4C3 of the controller, it will be clear that no movement of thelatter can then be effected, and when the tip l5 passes beyond thenotched edge of the foot it is impossible for the actuator to cooperatewith and move the controller. \Vhen, however, the exhaustion of fillingreaches the desired point, there will be no filling-induced movement ofthe feeler, and the actuator will remain operatively positioned, asshown in Fig. 5, when the bunter 21 impinges on the shuttle, and as thefeeler-carrier is moved forward by the lay as it completes its forwardbeat the tip of the actuator engages the notched edge 4:4 of thecontroller and moves the latter forward as the stroke of thefeeler-carrier is completed. The transmitter is thereby rocked on itsfulcrum, and the operation of the controlling means for the loom will beeffected. Should the controller jump forward away from the actuator orthe bunter away from the shuttle after engagement therewith, as may sometimes happen, it would not be material, for the feeler is then inert andthere is nothing to move the actuator relatively to the feelercarrier,and are engagement of actuator and controller will be effected when theformer catches up with the latter. Ordinarily, however, the engagementof the sharp end or tip of the actuator with the notch 44L in the edgeof the controller will be maintained when once effected until theactuator and controller have effected the operation of the transmitter.If the tip of the actuator passes above the top of the controller, nomatter how slight the clearance, there will be no actuation of thecontroller, while, on the other hand, if the tip is ever so little belowthe sharp edge formed by the top of the foot 43 and the beveled upperside of the notch 44 then the controller will be actuated. A verycertain operation is thus insured when called for and prematureoperation is completely eliminated.

A spring 46 is coiled around the stud a1 and fixed at one end, its otherend being connected with the controller o, the spring being so woundthat it acts normally to hold the controller in the low or rear end ofthe cam-slot 39, with the transmitter locked in inoperative 3 position.

The filling-exhaustion-indicating mechanism is manifestly adapted tocontrol either a filling-replenishing mechanism or a loomstoppingmechanism, either mechanism constituting means to control the operationof the loom, the filling-exhaustion indicating mechanism governing theoperation of such controlling means.

Various changes or modifications in construction and arrangement may bemade by those skilled in the art without departing from the spirit andscope of our invention, herein shown and described in one practical andefiicient form.
